portable mobile
visual field analyzer based
on VR system

                     Total Vision company develops innovative medical devices based on virtual reality systems. Our new device is the stimulus visual field analyzer (perimeter).

                     stimulus perimeter is designed to analyze disorders of the central visual field of a person.

The “decision support system” based on Artificial Intelligence increases the reliability and speed of diagnosis, saves money.

                     Today, with the help of the stimulus perimeter, it is possible to continue to provide professional medical services outside of inpatient medical facilities, even during a pandemic and quarantine, to ensure a healthy lifestyle and promote well-being for all people at any age.

what about the future...

The stimulus VR system can be effectively used in many areas of medicine and healthcare to solve a variety of tasks



  • infantile esotropia

  • amblyopia (lazy eye)

  • refractive errors

  • astigmatism, etc.


  • color perception (color test)
